4 Ways to Hook up Your Dishwasher to the Drain

   For most households, the dishwasher is a must-have appliance that makes cleaning up after meals a breeze. But most people don’t think much about how this machine works.  If you’re considering replacing or installing a new dishwasher yourself, you’ll want to be aware of how to hook it up to the drain before you get started. In this article, we’ll cover the four ways you can properly connect your dishwasher to your <a href="http://whittenplumbing.com/plumbing/residential/">plumbing system</a>.</p>
<p>The first decision you’ll need to make is whether to go with the high loop or air gap method. These are both approaches for preventing dirty dishwasher from coming back into your appliance. Some areas around the country require air gaps, so you’ll want to check your local codes.</p>
<p>After making that selection, you’ll need to know whether you’re connecting your dishwasher directly into the drain or into a <a href="http://whittenplumbing.com/garbage-disposals/">garbage disposal</a>, since that will change the way you install it.</p>
<h2><b>Connecting a dishwasher using a high loop.</b></h2>
<p>A high loop means that the dishwasher drain hose is installed so that there’s a U-shaped bend above the point where the hose is connected to the drainage system. You want to have this loop as high as possible, and attach it to the underside of the countertop underneath your kitchen sink.</p>
<h2><b>Connecting dishwasher to an air gap.</b></h2>
<p>With an air gap, there’s an additional part—usually a small, metallic cylinder—that’s mounted on top of your sink or countertop. The dishwasher drain hose connects to this air gap device between the dishwasher itself and the drainage system. One advantage of the air gap method is that is prevents water from siphoning if the dishwasher and sink faucets are draining at the same time.</p>
<p>Now that you know the two different draining methods, here are the four ways you can hook up your dishwasher.</p>

If you’re considering replacing or installing a new dishwasher yourself, you’ll want to be aware of how to hook it up to the drain before you get started. In this article, we’ll cover the four ways you can properly connect your dishwasher to your plumbing system.

The first decision you’ll need to make is whether to go with the high loop or air gap method. These are both approaches for preventing dirty dishwasher from coming back into your appliance. Some areas around the country require air gaps, so you’ll want to check your local codes.

Connecting a dishwasher using a high loop.

A high loop means that the dishwasher drain hose is installed so that there’s a U-shaped bend above the point where the hose is connected to the drainage system. You want to have this loop as high as possible, and attach it to the underside of the countertop underneath your kitchen sink.

Connecting dishwasher to an air gap.

With an air gap, there’s an additional part—usually a small, metallic cylinder—that’s mounted on top of your sink or countertop. The dishwasher drain hose connects to this air gap device between the dishwasher itself and the drainage system. One advantage of the air gap method is that is prevents water from siphoning if the dishwasher and sink faucets are draining at the same time.

Now that you know the two different draining methods, here are the four ways you can hook up your dishwasher.

  1. High loop to drain – Pull as much of the drain hose into the sink cabinet as possible. Make the high loop, then attach the end of the hose to the Y-branch tailpiece using a hose clamp.
  2. High loop to garbage disposal – Follow the same instructions as #1, except connect the dishwasher drain hose directly into the garbage disposal. You may need a dishwasher connector if the garbage disposal fitting is larger than your hose.
  3. Air gap to drain – After mounting the air gap device to the sink or countertop, you’ll attach the dishwasher drain hose to the small side of air gap. You may need to trim the hose, and be sure to use a hose clamp. You’ll need another piece of hose to connect the larger end of the air gap into the sink drain. Avoid having kinks in any of the hoses.
  4. Air gap to garbage disposal – Follow the same instructions as #3, except connect the larger rubber hose coming out of the air gap to your garbage disposal.

Installing a dishwasher can be a fairly easy project. However, it’s important that the drainage it properly set up to avoid having dirty water and bacteria coming back into your dishwasher and contaminating your dishes and utensils.
